Gradle Task: flywayMigrate

Migrates the schema to the latest version. Flyway will create the metadata table automatically if it doesn't exist.



> gradle flywayMigrate


Parameter Required Default Description
url YES The jdbc url to use to connect to the database
driver NO Auto-detected based on url The fully qualified classname of the jdbc driver to use to connect to the database
user NO The user to use to connect to the database
password NO The password to use to connect to the database
schemas NO default schema of the connection Case-sensitive list of schemas managed by Flyway.
The first schema in the list will be automatically set as the default one during the migration. It will also be the one containing the metadata table.
table NO schema_version The name of Flyway's metadata table.
By default (single-schema mode) the metadata table is placed in the default schema for the connection provided by the datasource.
When the flyway.schemas property is set (multi-schema mode), the metadata table is placed in the first schema of the list.
locations NO filesystem:src/main/resources/db/migration Locations to scan recursively for migrations. The location type is determined by its prefix.
Unprefixed locations or locations starting with classpath: point to a package on the classpath and may contain both sql and java-based migrations.
Locations starting with filesystem: point to a directory on the filesystem and may only contain sql migrations.
sqlMigrationPrefix NO V The file name prefix for Sql migrations
repeatableSqlMigrationPrefix NO R The file name prefix for repeatable Sql migrations
sqlMigrationSeparator NO __ The file name separator for Sql migrations
sqlMigrationSuffix NO .sql The file name suffix for Sql migrations
encoding NO UTF-8 The encoding of Sql migrations
placeholderReplacement NO true Whether placeholders should be replaced
placeholders NO Placeholders to replace in Sql migrations
placeholderPrefix NO ${ The prefix of every placeholder
placeholderSuffix NO } The suffix of every placeholder
resolvers NO Fully qualified class names of custom MigrationResolver implementations to be used in addition to the built-in ones for resolving Migrations to apply.
skipDefaultResolvers NO false Whether default built-in resolvers (sql, jdbc and spring-jdbc) should be skipped. If true, only custom resolvers are used.
callbacks NO Fully qualified class names of FlywayCallback implementations to use to hook into the Flyway lifecycle.
skipDefaultCallbacks NO false Whether default built-in callbacks (sql) should be skipped. If true, only custom callbacks are used.
target NO latest version The target version up to which Flyway should run migrations. Migrations with a higher version number will not be applied. The string 'current' will be interpreted as MigrationVersion.CURRENT, a placeholder for the latest version that has been applied to the database.
outOfOrder NO false Allows migrations to be run "out of order".

If you already have versions 1 and 3 applied, and now a version 2 is found, it will be applied too instead of being ignored.

validateOnMigrate NO true Whether to automatically call validate or not when running migrate.
For each sql migration a CRC32 checksum is calculated when the sql script is executed. The validate mechanism checks if the sql migration in the classpath still has the same checksum as the sql migration already executed in the database.
cleanOnValidationError NO false Whether to automatically call clean or not when a validation error occurs.

This is exclusively intended as a convenience for development. Even tough we strongly recommend not to change migration scripts once they have been checked into SCM and run, this provides a way of dealing with this case in a smooth manner. The database will be wiped clean automatically, ensuring that the next migration will bring you back to the state checked into SCM.

Warning ! Do not enable in production !
ignoreFutureMigrations NO true Ignore future migrations when reading the metadata table. These are migrations that were performed by a newer deployment of the application that are not yet available in this version. For example: we have migrations available on the classpath up to version 3.0. The metadata table indicates that a migration to version 4.0 (unknown to us) has already been applied. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway continues normally. This is useful for situations where one must be able to redeploy an older version of the application after the database has been migrated by a newer one.
cleanDisabled NO false Whether to disable clean. This is especially useful for production environments where running clean can be quite a career limiting move.
baselineOnMigrate NO false Whether to automatically call baseline when migrate is executed against a non-empty schema with no metadata table. This schema will then be baselined with the baselineVersion before executing the migrations. Only migrations above baselineVersion will then be applied.

This is useful for initial Flyway production deployments on projects with an existing DB.

Be careful when enabling this as it removes the safety net that ensures Flyway does not migrate the wrong database in case of a configuration mistake!

baselineVersion NO 1 The version to tag an existing schema with when executing baseline
baselineDescription NO << Flyway Baseline >> The description to tag an existing schema with when executing baseline
